MARCONI  MARINE UK -
SOME VINTAGE MARINE  ELECTRONICS
Some of the earliest equipment shown was reviewed in "The Marconi Review"  in date ranges from 1928 to 1930. This means that the equipment was designed and in service well ahead of the dates on which it was reviewed.  In the earliest days of radio the word "set" was used to designate an assemblage of components. This could mean two or more pieces of equipment that are interconnected to provide a particular function.
